Abstract: A method and apparatus for increasing capacity and performance of a base station for a sectorized cellular wireless network is disclosed in which one of the sector antennas is replaced or supplanted by a novel sub-sector antenna that generates a plurality of asymmetrical sub-sector coverage areas that collectively substantially cover the coverage area of the replaced sector antenna. The use of asymmetrical coverage areas permits the total coverage area to closely approximate the symmetrical sector coverage area without creating excessively large sub-sector handover zones or introducing severe degradation in the network performance. This in turn permits the selective replacement of a single sector antenna rather than the wholesale replacement of all sector antennas in a region, leading to lower transitional costs and the ability to provide a focused approach to capacity planning.

Abstract: A wireless communications system is disclosed in which first and second base transceiver stations are connected to an antenna having first and second diversity characteristics and channels. First and second inputs of a first 90° or 180° combiner are fed the first characteristic of the first channel and a characteristic of the second channel and first and second inputs of the second combiner are fed the second characteristic of the first channel and a characteristic of the second channel opposite to that of the second input of the first combiner. The summation outputs of the first and second combiners are fed to the main ports of the first and second stations and the difference outputs thereof are fed to the diversity ports of the second and first stations. If the characteristic of the second input of a combiner is opposite to the characteristic of the first input, amplitude nulls may be significantly reduced.

Abstract: A method and apparatus process the powers of a plurality of beamformed signals at those elements of a common antenna array in which power is concentrated, to minimize losses due to combining. Preferably, signal powers at such dominant elements are approximately equal and mutually orthogonal, and can thus be fed to a Butler matrix of suitable order, for processing substantially without loss. Signal powers at remaining elements may be combined in conventional fashion, any resultant combining losses being only a fraction of total available power, and weights of these remaining elements are adjustable for orthogonality of the dominant element. Alternatively, the antenna elements may be organized into a plurality of overlapping antenna arrays, in which signals intended for dominant elements are not combined but fed to different elements, with more sensitivity than would be obtainable by simply dividing or allocating antenna elements among the desired number of antennas.

Abstract: A tri-polar antenna element for a beamforming antenna array has a pair of mutually orthogonal slots defining a first plane incorporating azimuthal and elevation directions. Between adjacent array elements, 0.5 wavelength spacing is provided in the azimuthal plane and 0.8 wavelength spacing in the elevation plane. The elements are sufficiently proximate to avoid forming grating lobes in a radiated signal. A dual feed network and patch radiator extend along second and third planes, parallel to and respectively below and above the first plane. A linear slot bisects the azimuthal and elevation directions along the first plane in the additional 0.3 wavelength spacing corresponding to the elevation plane. A linear feed network extends along the second plane in the additional 0.3 wavelength spacing below the linear slot. The invention provides 1.5 increase in antenna elements density, smallest physical footprint, and improves available power output by reducing combination power loss.

Abstract: A method of beam forming is provided for an appliqué intelligent antenna system. The appliqué system uses a watchdog function to monitor broadcast channels of an existing mobile wireless base station to which it is attached. The appliqué system synchronizes itself in frequency and time to the base station. In GSM timing delays are used to prevent collision of timeslots from various mobile terminals. The appliqué system uses this time delay mechanism to compensate for its own processing delays so that its presence is transparent to the existing base station. Angle of arrival calculations are made to determining beamforming parameters. The antenna of the four element antenna system are separated by is (5 1)/2 times the wavelength. Angle of arrival for the strongest uplink multipath signal are used to direct the downlink beam.

Abstract: A patch radiator for use in beamformed or steerable antenna systems which maximizes upper frequency limit and simultaneously minimizes the lower frequency limit, by providing an annular patch configuration in which a central region of the patch element is devoid of material, whereby this central region is of a different shape from the shape of the exterior perimeter of the patch element. One possible configuration of such a patch radiator comprises a square exterior shape, enclosing a central circular region of removed material. In this manner, the upper frequency limit threshold tends to rise as the interior annular perimeter is reduced. Preferably, the exterior and interior perimeters have no interior angles of more than 180°.
